Abstract

A tire is provided with a ring-shaped tire skeleton member, a belt and a layer. The belt includes a resin-covered cord of the belt is formed of a reinforcing cord covered with a covering resin. The resin-covered cord is-wound on the outer periphery of the tire case in a helical shape in the tire circumference direction and is joined to the tire skeleton member. Portions of the resin-covered cord that are adjacent to one another in the tire axis direction are joined to one another. The layer includes a long and narrow cord member that is wound at an outer periphery at the tire axis direction end portion of the belt in a helical shape in the tire circumference direction. The resin-covered cord and the rubber-covered cord intersect as seen in a tire diameter direction.

Claims

exact text as granted — not AI-modified
1 . A tire comprising:
 a ring-shaped tire skeleton member;   a belt, in which a resin-covered cord is wound in a helical shape in a tire circumference direction at an outer periphery of the tire skeleton member and is joined to the tire skeleton member, portions of the resin-covered cord that are adjacent to one another in a tire axis direction being joined to one another, and the resin-covered cord being formed of a reinforcing cord covered with a covering resin; and   a layer in which a long and narrow cord member is wound in a helical shape in the tire circumference direction at an outer periphery of a tire axis direction end portion of the belt,   wherein the resin-covered cord and the cord member intersect as seen in a tire diameter direction.   
     
     
         2 . The tire according to  claim 1 , wherein the cord member is wound in the helical shape with portions of the cord member that are adjacent in the tire axis direction being spaced apart. 
     
     
         3 . The tire according to  claim 1  or  claim 2 , wherein the cord member extends over an entire range in a tire axis direction of the belt. 
     
     
         4 . The tire according to  claim 1  wherein, as seen in the tire diameter direction, the resin-covered cord and the cord member are angled in mutually opposite directions relative to the tire circumference direction. 
     
     
         5 . The tire according to  claim 2 , wherein the cord member extends over an entire range in a tire axis direction of the belt.
